【CodeChef】Turbo Sort

题目链接：Turbo Sort

用java自带O(NlogN)的排序就可以，java要特别注意输入输出。输入用BufferedReader，输出用printWriter。printWriter的速度比System.out快很多，参考StackOverflow。

代码：

 1 import java.io.BufferedOutputStream;

 2 import java.io.BufferedReader;

 3 import java.io.InputStreamReader;

 4 import java.io.PrintWriter;

 5 import java.util.Arrays;

 7 

 8 public class Main {

 9     public static void main(String[] args) throws Exception{

10         // TODO Auto-generated method stub

11         BufferedReader bf = new BufferedReader(new InputStreamReader(System.in));

12         int N = Integer.parseInt(bf.readLine());

13         int[] ar = new int[N];

14         for(int i = 0;i < N;i++){

15             ar[i] = Integer.parseInt(bf.readLine());;

16         }

17         Arrays.sort(ar);

18         

19         PrintWriter pw = new PrintWriter(new BufferedOutputStream(System.out));

20         for(int i = 0;i < N;i++)

21             pw.println(ar[i]);

22         pw.flush();

23     }
